Sound Vibrations

Fish have a special sensory organ located in their lateral line. With this
organ fish can detect underwater sounds and disturbances. This lateral
line is so sensitive it can detect a fish’s prey. An injured
minnow’s struggle is readily perceived. Sound and other vibrations
carry better underwater; therefore, be cautious to eliminate vibrations
that may be detected by the fish. Heavy footsteps while walking or wading
are to be avoided. Careless wading can cause the gravel to strike each
other alarming the fish. Boat noises are to be avoided. An aluminum boat
can sound like a bass drum. Carpet the boat’s floors and storage
areas to dampen the noise. Talking is poorly transmitted underwater,

although very loud noises can be conveyed. So go ahead and talk but
don’t vibrate the water. The basic rule is to avoid all motions
which cause underwater vibrations.

In summary, after judging each of these variables, plan your approach
carefully. Sometimes so many of these variables are stacked on the
fish’s side that a successful approach may be just too complex. It
would be better to find another fish. When these variables are stacked in
your favor, the approach may be as simple as walking or wading directly to
the spot that you want to fish. Remember that the approach plan should be
to remain out of the fish’s vision and hearing. Move stealthily
like a blue heron. Herons are professional fish stalkers, and much can be
learned by observing their methods. Make motions slowly and deliberately
and try to blend in with the environment. Dress accordingly with colors
and patterns that intermix with the background. Once in position, stop and
rest the fish; subsequently, the fish may accept the angler as part of the
landscape. Make your first presentation your best one.
